Application filed April 18,

This invention relates to a radio program exhibitor and has for its important objects to provide, in a manner as hereinafter set forth, a device of this character embodying ing a novel construction and arrangement of parts for automatically bringing into view a schedule of radio programs in the order 'of their occurrence, the invention further contemplating advertising matter adjacent each program.

' Other objects of the invention are to provide a radio program exhibitor of the character described which will be simple in construction, strong, durable, efiicient and reliable in use and which may be manufactured at low cost. 7

All of the foregoing and still further objects and advantages of the invention willbecome apparent from a study of the following specification, taken in connection with the accompanying drawings wherein. like characters of reference designate corresponding parts throughout the several views, and wherein Figure l-is a view in front elevation of a radio program exhibitor in accordance with this invention.

Figure 2 is a view in side elevation thereof with the door opened.

Figure 3 is a view in horizontal section taken substantially on the line 3- 3 of Figure 2 with the door closed and looking downwardly. I

Figure 4 is a view in vertical section taken substantially on the line 44 of Figure 2.

Figure 5 is a view in vertical cross section taken substantially-on the line 5-5 of Figure 4 looking to the right.

Figure 6 is a detail view in the clutch operating lever.

Figure 7 is a detail view in perspective of the spring winding stem.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a cabinet having a door 2 hinged for swinging movement on one side and further having an inclined front wall provided with the upper and lower windows 3 and 4, respectively A pair of vertically disposed, spaced 50 plates 5 and 6 are mounted in the cabinet i perspective of able actuating tool, such as a key. The stem 1981. Serial No. 531,227.

adjacent the permanently closed side of said cabinet and journaled for rotation in the plates are the horizontally disposed shafts'7, 8 and 9. The shaft'8 is j ournaled in the plate 6 through the medium of a winding stem 10 which, as best seen in Figure 7 of the drawings, is provided with a polygonal end portion 11 which projects through an opening provided therefor in the adjacent side wall of the cabinet 1 for engagement with a suit- 10 is journaled in the plate 6 and is provided with a cylindrical socketed-inner-portion 12 disposed between the plates 5'and 6 which rotatably receives the adjacent end portion of the shaftll. The stem 10 is further pro-- vided with a ratchet 13 which is engageable by a pawl 14 mounted on the plate 6 for retaining the stem against rotation in one direction. i i

The shafts 7, 8 and 9 extend from the plate 5 across the cabinet 1 and terminate in free end portions disposed closely adjacent the inner side of the door 2 when the door is in closed position. Spools 15 and 16 are removably and rotatably mounted on the shafts 7 and 8, respectively, and a roller 17 is fixed on the shaft 9. The ends of the shafts which are adjacent the door 2 are journaled in the apertured, resilient brackets 18 which are secured on the inner side of the door. The brackets which are engaged with the shafts 7,.and 8-engage the spools 15 and 16 in a manner to yieldingly urge said spools toward The lever 21 is further provided with a handle gortion 23 which is operable in a slot 24 in t e incline-d front wall of the cabinet.

A clock spring 25 encircles the cylindrical '100 projecting pin 27 which is mounted on said gear. The gear 26 is fixed on the shaft 8 between the plates and 6 and adjacent the plate 5. The gear 26 is continuously in mesh with a gear 28 fixed on the shaft 7 between the plates 5 and 6. An escapement movement designated generally by the reference numeral 29 and illustrated to advantage in Figure 5 of the drawings is mounted in the cabinet 1 between the plates 5 and 6 and operatively connected with the gear 26 for actuation thereby.

Fixed on the shaft 9 between the plates 5 and 6 is a disk 30 having diametrically opposite notches or recesses 31 in its periphery. A rocker arm 32 is pivotally supported, as at 33, intermediate its ends on the top of the cabinet 1 and has pivotally connected to one end an operating plunger 34 which is operable through an opening provided there-for in the top of the cabinet 1. Theother end of the rocker arm 32 is provided with a down turned lug which is adapted for engagement in the recesses or notches 31 of the disk 30. A keeper 35 is fixed on an intermediate portion of the rocker arm 32 for swinging move:

ment therewith, said keeper extending downwardly in the cabinet and terminating in an angularly disposed free end portion which is operatively engageable with one of the gears 36 of the escapement movement 29 for periodically locking the mechanism.

The reference numeral 37 designates a guide roller which traverses the cabinet 1 adjacent the lower side of the window 4. A

time disengage the clutch device on the shaft 8 from the spool 16, thus permitting rotation of said spool 16 independently of its shaft. As the tape travels over the roller 17, said roller 17 is actuated thereby, thus rotating the disk 30 which is also fixed on the shaft 9. At the completion of each half revolution of the disk 30, the lug on the end of the rocker arm 32 drops into one of the notches or recesses 31 in the disk 30. When the lug on the rocker arm 32 drops into one of the recesses '31, the keeper 35 is engaged with the gear 36 of the escapement movement 29 and the actuating mechanism for the shafts 7 and 8 is locked against movement until the disk 30 is released and the keeper 35 is disengaged from the gear 36 by pressing the plunger 34 downwardly as will be obvious. The spring 25 is, of course, wound through the medium of the stem 10 and the pawl 14 engages the ratchet 13 to prevent retrograde rotation of the stem. The spools may, of course, be actuated by hand if desired when it is wished to ascertain what programs will be broadcast considerably in advance of the time.

It is believed that the many advantages of a radio program exhibit constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the arrangement of parts may be resorted to which will fall within the scope of the invent-ion as claimed;

What is claimed is A radio program exhibitor of the character described comprising a cabinet having web or tape 38'is adapted to be wound fromWvindows therein, shafts journaled for rotathe spool 15 to the spool 16 and vice versa, said web or tape being trained around the rollers 17 and 37 and traveling adjacent the winddws 3 and 4 in a manner to be viewed therethrough.- As best seen in Figure 1 of the drawings the tape has on its outer side radio programs which may be viewed through the window, 3. Of course, any other indicia may be provided which may be necessary or desirable. The tape also may have thereon adjacent the indicia for each program suitable advertising matter to be viewed through the lower window 4. Different advertising matter would be provided with each program appearing on the tape.

In operation, the s ring 25 drives the shafts 7 and 8 in opposite directions through the medium of the gears 26 and 28. escapement movement 29, of course, controls the speed at which the shafts will be driven. When the tape is to be wound on-the spool 15 from the spool 16, the lever 21 is actuated in a manner to engage the clutch device on the shaft 7 with .the spool 15, thereby locking said spools to the shaft 7 and at the same The I tion in the cabinet, spools loosely mounted on certain of the shafts, aroller fixed on the other of the shafts, a spring'motor mounted in the cabinet and operatively connected with the shafts for simultaneously rotating said shafts in opposite directions, means for alternately connecting the spools with their respective shafts for actuation thereby, a tape windable on the actuated spool from the unactuated spool, said tape being trained over the roller for actuating said roller and having program indicia thereon, said tape adapted to travel adjacent the windows in a manner to be viewed therethrough, an escapement movement operatively connected to said certain shafts for controlling the speed of rotation thereof under the impulse of the spring motor, a diskfixed on said other shaft for rotation therewith and having notches in its periphery, a rocker. arm having one end slidably engaged with the periphery of the disk, a lug on said one extending through the casing and a keeper member having a curved lower end with its upper end fixed on the rocker arm for swinging movement therewith, the terminal of sand curved end being engageable with the escapement movement in a manner to lock said escapement movement and the shafts when the lug on the rocker arm engages in the notches in the disk. e

In testimony whereof I afiix my signature.
